The actor allocation will be invalid on CLUTTER_TOUCH_BEGIN, because it comes together with a CLUTTER_ENTER event that will recalculate styles, and queue a relayout in result. The net result is that on CLUTTER_TOUCH_BEGIN, the relayout has been already queued, so the slider width comes up as 0, and the value ends up as 1. Later touch events already happen on a validated actor, so it is corrected. Still, not fun when modifying the volume slider on a touchscreen.
